Put your jewellery on last, after perfume, moisturiser and sunscreen, and take it off first. We'd also take rings off for the gym, gardening, swimming and cleaning, where knocks and chemicals do the most damage.

Soak your ring in warm water with a drop of mild dishwashing liquid for about 20 minutes. Brush gently around and under the stone with a soft toothbrush, where oils and lotion build up, then rinse and pat dry with a lint-free cloth. A clean every few weeks keeps a diamond looking bright.

Skip harsh chemicals like bleach, chlorine and abrasive cleaners, which can dull or weaken the metal over time. We'd also avoid ultrasonic cleaners at home, as the vibration can loosen settings.

Every few months, have a close look at the claws holding your diamond. If a stone moves, a claw looks lifted or something catches on clothing, stop wearing the ring and email us at hello@unadiamond.com. Manufacturing defects are covered by our three-year warranty.

Plating is a thin layer of gold, so it lasts longest when it's kept dry and away from chemicals. Take plated pieces off before showering, swimming or exercising, and keep perfume, lotion and chlorine away from them.

Wipe it gently with a soft, dry cloth after wearing. Don't soak plated pieces or use jewellery cleaners on them, as both can wear the plating away.

Store each piece on its own in a soft pouch or a lined jewellery box. Diamonds can scratch gold, platinum and other diamonds, and plated pieces last longer kept away from air and moisture.
